Noctua NH-U14S, Premium CPU Cooler with NF-A15 140mm Fan (Brown)

Product Information

With six heatpipes, a fin surface area of more than 6000cm² and two highly optimised NF-A15 140mm fans, the NH-U14S TR5-SP6 provides a superior level of quiet cooling efficiency.

Topped off with the professional SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound, the NH-U14S DX-4677 forms a complete premium quality package for quietly cooling LGA4677 based Xeon workstations and servers. The compatibility indication is based on the height of the coolers (including fans) as well as the maximum CPU cooler height specification given by the chassis manufacturer. First introduced in 2017, Noctua’s Threadripper and Epyc coolers have become a standard choice when it comes to quiet, premium grade air cooling solutions for AMD-based workstations and servers. Excellent after sales service and support is included FOC, including some free upgrades should you change your pc. Nickel and nickel-base alloys generally have desirable properties that can withstand corrosive environments and high temperatures -- which are especially beneficial for a heat dissipation device.As only the bottom part actually contributes on the transfer of the thermal energy from the CPU to the heatpipes, this is a very reasonable design for the reduction of a cooler’s weight and overall cost. In the introduction of this article, I have asserted that someone being ignorant of the situation will bring huge surprises they have not been asking for. However, when your computer is idling or under nominal loads -- where it is probably going to spend most of the doing -- the PWM fan slowed down is almost inaudible. The quality of the cooler is also great, with very thick and strong mounting mechanisms and a completly unblemished array of heat fins. It being a Noctua product, I already expect top notch quality and low noise levels, but it still warrants a thorough look to see what is offered.

While the large, six heatpipe design and the NF-A15 140mm fan with PWM support for fully automatic speed control allow the cooler to best the renowned quiet cooling performance of all other U-series coolers, its 52mm slim shape still guarantees full compatibility with tall RAM modules on LGA2011. This heatsink is not the Tiburon who was unaware of the situation and ended up with a nasty surprise.Therefore, it is unsurprising the Intel Core i5-2405S CPU equipped with the bigger cooler performed better. Topped off with the pre-applied NT-H2 thermal compound as well as the professional SecuFirm2 mounting system for TR5/SP6 that has been updated to meet the platform’s increased pressure specifications, the NH-U14S TR5-SP6 forms a complete premium quality package for quietly cooling TR5-based Threadripper workstations and SP6-based Epyc servers.
